WHIP-ROLL FOR LOOMS.

Specification of Letters Patent.

Patented Nov. 9,1920.

. Application filed March 19, 1920. Serial No. 367,069.

porting-arms may be readily repaired afterv their bearings have becomeso worn as to be more or less useless, as more fully hereinafter setforth.

In the drawings Figure 1 is a side elevation of a whip-rollsupporting-arm provided with my repairbearing;. i I

Fig. 2 is a plan view thereof;

Fig. 3 is a side elevation of a common form of supporting-arm,as itappears before the bearings are worn.

The whip-roll is shown at a, one of its supporting-arms at b and itsoscillating supporting-shaft at 0, these being constructed as usual. Oneof the arms for supporting the shaft 0 is shown atd, this arm blein ofthe usual construction except that t e made in accordance with myinvention. The usual construction of. this arm at before it is worn isshown in Fig. 3. It will be observed that. it is rovided with twobearing-notches e, e. 11 use, the outer bearing 6 wears away, as shownby dotted line f, thus destroying the utility of the entire arm andrequiringthat it be taken off the loom and "discarded and replaced by'a' new arm. With my invention, I can utilize this arm notwithstandingthe fact that the bearing is worn to the extent of becoming useless as asupport for the rock-shaft c. In utilizing this worn arm, I mill awaythe transverse rig g upstanding between the two bearing-notches, thisbeing milled down to the dotted line 71,. I then fit into this widenednotch a wooden block i and fas-' arm bored for the s ecial purpose ofreceiving this. bolt. This locki is provided with a rounded notch kwhich forms a new bearingffor the rock-shaft c. Inthis rounded caringfor supporting the shaft 0 is for receiving a lubricant, and a notch isformed a depression Z which is adapted to be filled with tallow orx someother material which will not onlylubricate the bearing but willwo'rk'into the body of the block and thus render the same virtuallyselfdubricating. Of course, the tallow deposit is r'enewed from time totime, but,as the wood becomes more and more impreg nated with thetallow', a lesser quantity is re uired for proper lubrication.

ith my invention, it will be obvious that I save the waste heretofore,involved in junking the worn arms at. As the bearings in these armswear quite rapidly, this is a very material saving, and particularlybecause of a fact which I have found from experience, namely, that thenew or repair bearing lasts much longer than the original bearing andalso results in li hter running of the whip-roll mechanism. Thewhip-rollshaft 0 of course also becomes worn at the points ofimpingement against thebearingroll mechanism and also prevent theworndown surfaces of the shaft 0 from cutting the wooden blocks.

The nature and scope of the invention having been thus indicated and itspreferred embodiment, having been specifically described, what isclaimed as new is:

1. In a whip-roll mechanism for looms. a supporting-arm for thewhip-roll-shaft having a widened notch in its upper side a wooden blockfitted into this notch, said block being provided with a bearing-notchfor receiving the shaft of the whip-roll and said notch being providedwith a de ression olt for attaching the block to the arm.

2. In a loom,- a whip-roll-arm provided with a'notch, a wooden blockfitted snugly in said notch and provided with a bearingnotch, and meansfor fastening this'block A in its seat. I

In testimony whereof I hereunto afiix my signature.
